This invention relates to a unit conveyer for concrete product machines, the general object of the invention being to provide means for conveying'concrete blocks and the like from the machine to a distant point without re-f quiring the use of manual labor and in such a manner that there is no danger of the products being broken or damaged.

Another object of the invention is to provide means for adjusting the height of the conveyer cables adjacent the machine so that the cables can be properly positioned in relation to the delivery part of the machine to receive the products therefrom without jars or shocks.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter more fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, ref

' erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the invention,

this figure showing a part of the delivery means of the block forming machine.

Figure 2 is an enlarged view of the height adjusting means for the front end of the conveyer cable.

Figure 3 is a plan View of the forward part of the cable and their supporting wheels and the means for adjusting the height of the cables.

Figure 1 is a section on line 44; of Figure 3.

Figure 5 is a section on line 55 of Figure 2.

Figure 6 is a section on line 66 ofFigure 2.

Figure 7 is a section on line 77 of Fig-- ure 2. a Figure 8 is a perspective view of the yoke frame for supporting the shaft of the small wheels at the front of the conveyer.

Figure 9 is a plan view of the cradles. m In Figure 1 the automatic feeding means of the machine is shown generally at A and the cables which form the conveyermeans are shown at B. These cables are-driven from the power wheels; 1 and pass over the Wheels 2 supported by the framestructure 3 and over other wheels, a pair of which are shown at 1. Adjacent the block forming machine the cables pass-over the large wheels '5 and the upper reaches of the cables pass over the smaller wheels 6. The shaft 7 of'the wheels 5 is journal'led in the front ends of the horizontal bars 8 formed on the upper faceof the frame or cradle 9 which consists of two'side members 10 and a pair of cross members 11 which connects theside members together. I The large cylinder 12 is supported on the front end of a base 13 and the cross piece 14 is connected to the upper end-of the column and has a threaded hole therein to receive the threaded'shaft 15, the upper end ofwhich passes"thrOugh-aJhOle in the front cross piece 11 and has nuts16 threaded thereon one above thecross piece and-the other below the same.

. Thus by adjusting these nuts on theshaft 15,- the e front end of the cradle 01" frame 9 can be raised andlowered 'to adjust the height of the wheels 5which in turn of course adjust the height of the'front end'of the conveyer.

' A pair of columns or cylinders 17 have their. lower ends connected with the rear part of the base 13 and the upper ends of these columns or cylinders are closed by a'plate 18 which is provided with a pair of threaded holes, one communicating with each cylinder or column and threaded shafts 19 passing through these holes and each shaft has a head 20 on its upper end for engagingthe rear cross piece 11 when the shafts or bolts 19 are passed' through the-holes 21 in the cross piece Nuts 22 on the shafts or bolts 19 engage the lower face of the crosspiece-ll to fasten'the shafts'or bolts to saidcr'oss piece. Thus by adjusting these belts or shafts in the plate'18, the rear end of the frame or cradle'9 can be adjusted to adjustthe front end ofthe conveyer cable.

A yoke-shaped frame 23 has the free ends of its limbs pivoted to the shaft 7 and these limbs,adj acent the bight ofthe frame, carry theuprights 24 which formbea'rings for the shaft 25 of the wheels 6. The bight of the frame'23 rests upon the heads26 oflongbolts 27 which pass through the holes 28 in the cross piece 11 and through holes in the plate 18, these last mentioned holes not being threaded. Nuts 29 are threaded on these bolts and engage the top face of the plate 18 so that by adjusting the bolts 27 the rear end of the frame 23 can be adjusted vertically as to raise or lower the Wheel i n Thus it will be seen that the cradle or frame, cables passing over the first-mentioned wheels with their upper reaches resting on the second-mentioned wheels and supporting means for the cables located rearwardly of the above-mentioned wheels and their sup porting means.

In testimony whereof I atfix my signature.

frame 9 can be adjusted vertically as well as l the yoke shaped frame 23 which permits the wheels 5 and 6 to be accurately set to hold the front ends of the cables B in a position so that they will receive the blocks or the products of the concrete machine from the feeding means of the machine withoutv giving the:

supported on the frame'3 and each having 1 a wheel 31 at one end thereof for engaging the lower reach of the cable with a threaded rod 32 at the other end of the bell so that the rod receives a nut 33. The rod is pivoted to the frame 3 as shown at 34 and by moving the nuts 33 the bevel cranks are moved so that the wheels 31 will apply'the proper tension to the cablesas shown in Figure 1.

. It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the com-. bination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claim; v Having thus described my invention, what I claimas new is: 1 T p A conveyer of the class described comprising front and rear uprighthollow members, a horizontal frame including a pair of spaced horizontal bars, vertically arranged screw shafts passing through threaded holes in the upper ends of the upright member and having their upper ends connected with the frame,;'a shaft passing thru the front ends I of the horizontal bars, apair ofwheels atq tached to said shaft, a yoke shaped frame having the ends of'its limbs pivoted to the shaft, uprightbearing members on thelimbs of the yoke shaped frame adjacent its bight part, a shaft carried by said bearing members, wheels carried by the shaft, vertically arranged screwshafts carried by the rear upright member and having their upperends engaging the, bight part of the yoke-shaped
